My 4-year-old daughter is always telling me she's going to marry her 1-year-old brother. Knowing that she won't actually do it, I just enjoy the sweetness of this time. Because more often than not, it really is sweet.

My little guy is mildly obsessed with the idea of marrying his little sister (two years younger than him). He is always saying how pretty she is, and that he wants to marry her. And he's already figured out that she's a girl and his friend, so she must be his girlfriend! And she adores him, too. I am hoping the day will never come when they don't want to hug and love one another as siblings because of "eeeeew! gross! but she's my sister/he's my brother!" sort of reasons...
